赋值的左侧必须是变量 Selenium webdriver XPATH

Question

我正在使用 Selenium webdriver 自动化网站，下面是代码，代码失败并显示错误消息

The left-hand side of an assignment must be a variable for identifying the login field using the XPATH, I am using XPATH since the ID and name are already failed and when I use the XPATH the below error message is populated, please help to correct the code

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

public class FirstClass {

    private static final String SeleniumWait = null;

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", 
       "C:\Users\Documents\Selenium\chromedriver_win32\chromedriver.exe");

        WebDriver driver = new ChromeDriver();

        driver.get("https://www.amazon.com/");
        driver.findElement(By.id("nav-link-accountList")).click();
        driver.findElement(By.id("signin")).click();
        WebDriverWait wait = new WebDriverWait(driver, 60);// 1 minute 
        wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("//*
        [@id="ap_email"]")));
        //chrome.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        driver.findElement(By.id("//*      
        [@id="ap_email"]")).sendKeys("testtest@gmail.com");

        /*driver.findElement(By.id("ap_assword")).sendKeys("Teachme100$");
        driver.findElement(By.id("signInSubmit")).click();
        //driver.close();*/

        /*WebElement ap_email = (new WebDriverWait(driver, 10))



       .until(ExpectedConditions.presenceOfElementLocated(By.id("ap_email")));*/
    }

    public static String getSeleniumwait() {
        return SeleniumWait;
    }

}

Answer 1

好像打错了。你能把双引号 (") 改成单引号 (') 吗？

driver.findElement(By.id("//*[@id='ap_email']")).sendKeys("testtest@gmail.com");
